  What roles are vital to a trauma team - ANS The patient Team leader-organize team/empower members core team-technical skills- airway/vascular access contingency and support services- RT Characteristics of an effective team - ANS dynamic interdependent adaptive common goal COMMUNICATION COOPERATION COORDINATION Kinematics - ANS study of energy transfer as it applies to identifying actual or potential injuries Biomechanics - ANS general study of forces and their effects mechanism of injury - ANS how external energy forces in the environment are transferred to the body Newtons 3 laws - ANS 1. an object in motion will stay in motion 2. force = mass x acceleration 3. for every action there is an equal and opposite reaction 5 forms of energy that exist - ANS 1. Mechanical- energy transfer from one object to another in form of motion 2. thermal-heat transfer from environment to host 3. chemical- heat energy trnsfer from active chemical substances such as chlorine, drain cleaner, acids 4. electrical- energy transfer from light socket 5. radiant- energy transfer from blast sound waves, nuclear, rays from the sun eternal forces in trauma - ANS 1. deceleration- falls and collision = sudden stop 2. acceleration- sudden onset of motion- hit by a car 3. compression- hit stationary objects; bullets; blast forces internal forces of energy in trauma - ANS stress- internal force that resists external force solid organs good at pressure wave energy air organs better at shear forces 4 main types of traumatic injury - ANS 1. blunt trauma- falls; mvc; trauma 2. penetrating- stabbing; GSW 3. Thermal 4. Blast Trauma- bomb deceleration vs acceleration forces - ANS -Deceleration: injury that occurs as pt slows down acceleration injury: injury that occurs as a result of other parts of the body stopping before the organs do (concussion; shearing of aorta) environment and pathophysiology when MOI is a fal - ANS -point of impact on the body -type of surface that is hit -tissues ability to resist injury (bone is less flexible) -pt pushed = more acceleration 3 impacts in a MVC - ANS 1. vehicle hits another object: occupant = acceleration 2. occupant collides with interior of vehicle: internal organs continue 3. internal structure collide with body 5 mechanisms of injury in a blast trauma - ANS Primary: blast injury; air-filled organs at risk to rupture secondary: fragment injuries; puncture wounds; lacerations tertiary: impacts with larger objects propelled by the blast win causing blunt trauma quaternary: heat/flame/gas and smoke quinary: exposure to hazardous materials (radioactive) Haddon Matrix in prevention and reduction of injury - ANS places emphasis on countermeasures at preventing injury more than changing human behavior such as airbags, vehicle design and road blueprints why is there repeated emphasis on assessment for hemorrhage through the initial emphasis - ANS uncontrolled hemorrhage is the major cause of preventable death after injury Which tool can be used to rapidly assess the level of consciousness during the A - Airway and Alertness step? Why is it important to determine alertness along the airway? What are the components of this tool? - ANS A- alert *any below here may have compromised airway V- verbal stimuli P-painful stimuli U- unresponsive Which method of opening the airway is recommended for use in trauma? - ANS Jaw thrust maneuver w/ one provider stabilizing c-spine Assessment of airway - ANS Insect for tongue obstruction; loose/missing teeth; foreign objects; blood, vomit, secretion; e
